If you can screw all the way into the stud no. If you cant screw to the stud then you need it.

For small parts, is there any reason to get a mill and lathe separately instead of a combination of both?

>>1598327
They work in completely different ways, what fucking combo are you looking at?

>>1598329

I have an idea for a product that I know is viable, but I don't think I will be able to develop it properly, does anyone know what the process is like for hiring someone to design/blueprint a product, and what sort of costs are associated, or do you sell a share of the product?

>>1598334
I don't lurk the >>>/biz/ board, but that's the only thing I can come up with ATM.
Grab a Shark Tank image and ask them.

>>1598327
Separately are almost always better. And don't buy grizzly

>>1598334
Is it something machined? I want to sell some of my time to prototyping if so.

>>1598327
> is there any reason to get a mill and lathe separately instead of a combination of both?

Smithy and pretty much every combo machines are terrible.
They are huge compromises to both machines.

>>1598373
>>1598376
Oh okay, thanks. Would you guys recommend anything in particular?

>>1598377
Tormach because cnc is amazing. If you must be as cheap as possible then precision Matthews machines are a step up from grizz

>>1598377
Are you gonna want to sit there cranking handles and eating chips and smoke? Then cnc is necessary if not

>>1598380

seriously of all things this is your reasoning

a little bit of chips and and smoke

>>1598377
Used

>>1598374

It would probably be machined, but there is a good chance a large part/all of it will be plastic.

Anyone know what kind of molex this is? Bought a used fridge and this one part is missing and hooks up power to the temperature regulator...

>>1598427
It connects 5 pins in a circle
been looking for fucking ever and nothing

>>1598428

replace it with something else from ebay or an auto supply store or even wire nuts.

>>1598481
Already checked, whatever it is, it's not on there.

>>1598430
Mmmm, I'd happily use whatever, but I don't know what the connector is called, wire nuts definitely wouldn't work though.

>>1598487
Just cut it off and put whatever 5 pin thing on it you can find

I am trying to disassemble an old signal meter to fix & clean it. One of the potentiometers on the thing has a knob that I can't get off because the set screw is stripped. Any advice for how to get it off? Should I just drill the screw out?

>>1598869
I meant signal generator.

I'm looking for a corded reciprocating saw to use to take down and subsequently chunk up a wooden shed and on a few other small projects around the house. Something cheap would be good because I probably won't use it a ton, but I see that a lot of them like to lose their blades, which sounds annoying and potentially dangerous. Does anyone know if I can get anything half-decent for about $90 or less?

>>1598869
>Should I just drill the screw out?
The half that's still in place will make it difficult to center the bit.
Start with the smallest bit you have and use it as a mill to cut into the flat of the remaining slot piece.
Then work a hole as close to center as you can.
Very small screw extractors are available.
I have an EZ-Out with the stub of a #4 screw still stuck on it to remind me that if I'm careful, I can do it.

I got a sixteen dollar one from harbor freight. I leave it out in the rain and cut trees and treated lumber and treat it like shit. Its been doing alright for five years.

what would make a squealing noise when I depress the clutch for the P.T.O.? still seems to work, just complains about it

I have a stream in my back yard that has eroded a sizeable chunk of land out. I have diverted the stream and need to backfill the erosion now.

Can I use tree logs and fill voids with dirt over a couple years or just splurge on extra dirt/rock?

>>1598978
And blade slippage? I guess it doesn't matter how long it lasts if it's only $20, which seems to be how HF operates in general.

i have a small diesel engine which i want to control the speed of electronically
it has what appears to be a stepper motor installed alongside the pull throttle, with 4 wires coming out of it, which would make it a bipolar stepper motor, however, it then has a small tube in-line with it, which only has 3 wires out the other end before the connector
the tube and motor housing are both potted, with no identification on them
is this a standard configuration? or otherwise is there a safe way to test what the 3 wires expect to control the motor? i could just cut out the tube, but i'd rather not if i don't need to
getting a spare to remove the potting isn't feasable

>>1599064
-- oh, also, the engine is a chinese clone of an unknown engine, so i have no information about it

I need a soldering iron that is wireless (so not a weller or hakko desk set) and was thinking about the ts80 because its USB, but i dont know a ton about soldering irons.

is that a good choice or are there better options out there for wireless/portable soldering irons?

>>1599165
you can get butane soldering irons (butane torch with a soldering iron tip, basically)
i've never seen USB soldering irons before, i'd imagine they'd take some time to warm up, 5V@2A is only 10W of power
that and butane ones are actually wireless

>>1599165
Honestly, seconding >>1599176
Butane tips actually work fantastic if you've got ventilation.

>>1598031
Should I use double sided tape to put the baseboard? Silicone caulking?

Has someone tried this with some extra-strong tape like this one?

https://www.amazon.com/tesa-55791-00000-00-Ultra-Strong-Mounting/dp/B00BJH3N0M/

>>1599165
You already got your fucking answer in the thread you made weeks ago.
Get a ts100, and get a 5S battery pack, and a little adapter cable. It alternatively runs on whatever laptop power cord or cigar lighter cable, ect 12-24v source you can find.

Getting a portable air conditioner for my apartment. I want to vent it out the sliding glass door to the balcony but the included window kit probably won't be large enough to fill the space (meant for a sliding window) any recommendations to fill in the gap? Should I just cut some plywood or something or is there something better? They sell kits for this but it's like $99 and fuck that

>>1599441

You can definitely make one, but OSB would last longer than plywood, is cheaper, and easier to work with. Paint tends to peel from plywood but bonds well to OSB.

Whats the cheapest place to get these V mounts for LED strips? I need 15meters of it, and am in Canada.(i assume i'll need to order it online, since places like leevalley are like 3x more expensive than chinese sellers.. Just looking for the cheapest chinese seller)

>>1599444
Thanks I'll try that instead

>>1598031
How I'm supposed to clean those mini-splits?
I have slight stench coming from it, and it kinda gets slowly dusty.

>>1599474

Hey, I've got a scratch on the inside of my windshield. It's not interfering with my driving or anything but I get mildly annoyed every time that I see it.
Anybody knows a good way to make it go away? Fill it with something?

>>1599176
These work great if the work is not very sensitive.

>>1599491

dont worry

tomorrow your windshield will be a whole lot worse

>>1599064

not standard

not hard to take apart to find which wires are power/ground/vref/etc

>>1599840
alright, looks like i might just have to dismantle the tube and figure it out, failing that, just drive the motor directly
thanks for you response

>>1599838
It's tomorrow, my windshield's fine.

I have LED plant lights that I'd like to concentrate the beam of. I'm planning on building rectangular box for two lights, let's say it's 1' x 3', I'd love for the light not to scatter outside of a 1' x 3' rectangle all the way down to the floor - I want vertical beam of light. Are there any sort of sheet lenses like TV fresnal lenses that do this? A sheet of vertically arranged optical fiber would do it I think, not sure what to search for that though - or at least I'm not finding anything

>>1600179
And put foil tape on the top of your box.

>>1598950
>reciprocating saws
>losing their blades

The fuck? Even cheapshit ones don't "lose" the blade; working the absolute piss out of cheap blades you might BREAK them but the collet that holds them in the tool itself is usually not a point of failure.

>>1598978
>$16 one from HF

Basically same story here I have the base model Chicago Electric one with the pivoting body that's always on sale/coupon for $20 and it's served me well for several years even though it definitely sounds and feels like a pile of shit. Most likely failure mode will be brushes/electronics from overheating but using the right blade (even a cheap one) for the job and minding the temperatures will let it serve loooooong beyond its price point.

>>1599061
As above, the blades don't slip in the tool itself assuming you put them in correctly, and any other "slip" you could be talking about sounds like user error/mistake.

The mains for the light fixtures go through a plastic tube that's bent and juts out from the ceiling.
Can I just push back the wires and drill into the tube to enlarge the hole for a different light fixture? Or are we getting into illegal territory?
I don't have a picture, but just imagine a brown and blue cable hanging from the ceiling.

>>1599021

>>1600396

I'm looking to grind some spare cash with my tools. I've got all the usual Woodworking stuff other than a lathe - what is selling like hotcakes right now?

>>1600479

I've never bought a hotcake in my life.

>>1600480
Me either, now that I come to think of it.

>>1600466
It's not supported by the tube, it's just that the mains come through the tube straight out of the ceiling.
specifically the wire mount for the fixture is too large to fit in that tube, and since that mount juts out above the fixture it has to have a space where it fits inside the ceiling.

>>1599466
Honestly for that amount amazon is barely more expensive than aliexpress and you will get it now instead of in 3 months plus you will have amazon's return policy if you get warped pieces.

I am moving into an apartment with a spare bedroom, I'd like to finally get some tools and set up a hobby shop. I'll probably craigslist a nice drill press, I also want a cutting device - leaning towards band saw. What materials will I not be able to cut with a 9" band saw? I'd like to be able to cut acrylic, resin blocks, aluminum c channel and similar bars, thin stainless sheet. Will I be able to get a perfect cut when using the rail? Or is the cut edge always going to be more rough than a table saw?

>>1599983
problem solved

>>1600561
Unless your blade miraculously has no flex to it and the saw has a perfect setup, you cannot get as perfect of cuts as on a table saw. If you're not doing super precise work, you'll be fine, but a table saw is just better for big, long, fairly consistent cuts.

So I had a Trek xcaliber 8 when I was younger and my little brother got it out after it being in the shed for 4 years and all the cables are fucked on it, except the suspension lock/unlock cables.
So I was wondering how many packs of like shimano cables and outer cables will I have to purchase to replace the whole thing?

How in the ever living fuck do you get these out of the wall ? Help me diy you're my only hope

>>1600798
Drill them out with metal drill.
or
Patch them over with mud

>>1600798
Assuming they're threaded, if you have the bolts that go with them you can turn them in about a quarter inch then pull them with a hammer, or pry bar, like you would a nail. Then patch with mud like Anon said.

A video explaining why you NEED the screw https://m.youtube.com/watch?v=awHvbBOMjhQ

I've got a concrete slab slanted to one side because that end sank into the soil - it's about 11'x6', what's my best option if I want to pry it up and just pour sand underneath to level it? I don't want to pay to get it mudjacked.

I want to get my sister some knitting needles made from tungsten or tungsten carbide. I'm not really familiar with either materials' properties other than that they are heavy and hard. Which would be better for 10"-12" length without breaking/shattering? How thick would these need to be? Maximum practical thickness would be ~0.25", and I see some fairly affordable ones on ebay at ~0.09".

>>1600842
Yep pry it up. Or Jack it up use dirt though. Sand will wash out.

>>1600622
>mcshityourpants
No self-respecting American eats that crap.
Just because "HoneyBooBoo" is on TLC doesn't mean we all look like her.

put the screw back in but only thread it about 3-4 turns
tap on the head of the screw with a hammer
if the drywall is sound, you should be able to straighten the legs back out if you work carefully
you can tell when they're straight because the head of the screw will be flush with the anchor
then pull it back through the hole
the legs won't be perfectly straight so the hole will be about the same size as the part you see exposed when you pull it through

or, use a small, sharp blade to cut around the exposed head and push it in so it's under the surface (or all the way through the drywall) then cover it with spackling

or, take a pair of needle-nosed pliers and fold the head in half
most of the time the head will break off and you can push the core into the cavity

>>1600842
>what's my best option if I want to pry it up and just pour sand underneath to level it?

I just want lighting in my basement that doesn't suck without burning it down (though a housefire is a light source) or killing myself, since I don't deal with electricity a whole lot. Apparently, all the fixtures behind the drop down ceiling have been plugged in to some distant outlets above said ceiling, and it looks like replacement panels all expect you to hardwire things in.

How difficult would it be to replace a window in a wooden-framed brick-clad house? I have some light DIY experience (patching drywall, doing some electrical, pool maintenance...). I dont even want to replace it for some fancy new "green energy double pane eco friendly" stuff; the existing window is misaligned with the track on the frame so it doesn't open and close properly (but it is still weathertight).

personally I recommend a butane soldering gun in every kit just because you will run into a ground plane that screams fuck you at you for even trying to solder it with your peasant shit.

but if you are just connecting wires that aren't thick, a usb soldering iron can work, just know ahead of time it will be overall garbage.

Hi,
I made some particle board shelves for stuff in my room, but even thought I wore a mask while cutting it, should I be concerned by the "open cuts" at the boards edges? They are gonna stay in my room for a long time so Im concerned.
Should I put primer on them? Or how should I treat them?

>>1602091

>>1602091
Covering them up won't stop the off gassing. It's okay, it's just a little formaldehyde, the EPA has totally determined it's a safe amount for you to be exposed to. Just don't redo your whole home at the same time.

Is it feasible to make a kitchen knife out of a stainless steel scraper or something similar? I hate the geometry of most kitchen knifes so I was thinking about making my own.

>>1598036
not necessarily, depends what you're trying to mount. also those spinny bois don't hold nearly as well as the standard anchors

>>1602586
something like this, super simple geometry. I'm just not sure if a bench scraper or something like that is the right steel to make a knife out of. Oh and I only really have handtools available to me, I'd just really like to get that done somehow.

I'm thinking of putting a floating set of bookshelves up, I'm thinking 4 shelves framed up with the "backing" just being the wall. What species of wood is good for this? I think cherry would be very strong, but if pine will do the job I'd prefer that. I'm just concerned about the shelves (4ft wide, I'm thinking) bowing with softer woods.

I am trying to calculate the force needed to stretch a piece of natural latex rubber. I am having some problems

Supposedly the Young's modulus of latex rubber is around 50 MPa.

Therefore, to stretch latex with 1 m2 cross-sectional area by 100%, I need 50 million N per meter length, correct?

So if I have 1 cm2 cross-sectional area, that would be 1/10000th of it, so 5000 N per meter, or roughly 500 kg.

But that can't be true. So where is my mistake?

>>1603056
Never mind, I found another source that gives the Young's modulus as 1-5 MPa instead of 10-100. That seems more realistic

>>1602588

On a european electrical outlet, is it possible to determine which hole is the phase and which is the neutral ?
If I stick a single voltmetre probe in the phase, would it show a tension ?
I tried with a phone charger, and it wouldn't show a tension unless I put the other probe on the neutral, however it's continuous current so it might be different.
I'm a bit scared of trying with a live 230V outlet and finding out myself.

>>1603161
most multimeters will have a ac and dc voltage setting.
the AC will be set for your line frequency and do some kind of RMS fiddling.
also normally the AC setting will show polarity.
how it does this is black magic and wizards.

>>1603165
>also normally the AC setting will show polarity.

Actually it won't because it can't, unless there's a third lead that you ground. And by "polarity" I assume you mean live or hot vs. neutral. The hot wire goes positive for one half cycle, then negative for one half cycle, so there's no polarity to it in general.

Or did you mean DC?

Go to the junkyard. Cars come in from accidents with good batteries all the time. Otherwise get in good with somebody at a shop or auto parts store or whatever, you can probably cop a good battery from some dumb boomer with a dead alternator who replaced the battery too. You better test it under load though.

Otherwise Walmart is probably the cheapest for new batteries. Certain uncommon sizes are even cheaper. Northern Tool sells lots of smaller lawn equipment sized batteries as well, I had to replace a starter battery on a generator and for some reason this little AGM battery was on sale/clearance for <$20 when everybody else was asking $40+.

>>1598334
I'll say one thing, at least you are smart enough to realize you can't do it yourself. I watched my dad throw away maybe 250k trying to get a product off the ground ( and that was just his portion ).

How much money do you have to spend on this:
1) Under 1000
2) 1000-5000
3) 5000-25,000
4) 25k+

I say this in the kindest way, but ideas don't mean dick. At the exact moment you came up with that idea 1000 people had already thought about it, and every month 100 more people will have that idea. So the first thing you need to do is find out who else is doing it, has tried it, and who has patents on it.

If you are lucky someone is already doing it, and there isn't a patent, and they are mildly succesful. That means they have already learned the hard lessons, and you can try and copycat / improve on it, and hopefully you can both get rich. Good example of this is drop shipping from china in the 90s. You want to be on the early wave of something profitable, with other people to learn from.

Now, you think you have an original idea, and don't want to share it, and just want someone to put in all the hard work of getting it done. I get it. I've been there. Unless your answer to my first question was "I have $100,000 to spend" you will have to do a lot of shit yourself, or learn how to get investors. If you are from a major city, there will definiely be some sort of "tech incubator". or "inventors group". If you tell me the major city near you I can help you find one. Here are some of the major hurdles:

1) patents
2) building a proof of concept / prototype
3) getting investors
4) manufacturing
5) marketing and distribution

I did a provisional patent myself, and it was a lot of fucking work. Or you can pay a lawyer $5k+ to do it for you. What I did was get the provisional patent - then you have a year to be protected, and submit the real patent application. During this year you need to prove your product is viable, get investors, and pay for hte full patent.

I have a welder I need to power. I need 120v and 24 amps, the circuits are all either 15 or 20 amps with a double pole 40 and 30 amp. The 40 amp one goes to my oven, it's a three prong outlet. Two of the prongs are hot 120v 40amps and one neutral. Could I attach the hot and neutral together and attach the ground to a piece of rebar in the ground? Is there a required depth?
If it's too risky I'll run a ground wire to the panel.

>>1603722
>Could I attach the hot and neutral together
That's called a 'short' and will trip the breaker immediately.
>also lots of sparks and chance of fire

What's the safest/most legal way to transport a sheet of plywood strapped to the roof of a car? I have no access to a pickup truck and I have a doghouse I want to finish. Do I just use ratcheting straps and tie/nail a red caution tape flag to the ass end?

Just saw these on humble bundle. Are they any good?
https://www.humblebundle.com/books/electronics-3d-printing-make-books?hmb_source=navbar&hmb_medium=product_tile&hmb_campaign=tile_index_7

>>1603804
To the welder, silly

>>1603826
Pretty much. Two straps, one through each window. If you are anxious and you can manage it, a third or rope that runs lengthwise to stop it sliding back.

>>1603831
Make or purchase an adapter cable (pigtail)
leave the ground wire disconnected
in spite of what you'll be told here, you won't die if it's not connected

>>1603826
>a sheet of plywood strapped to the roof of a car
make sure the front of the sheet is flush with the roof of the car
If you can prop up the back end a few inches with folded cardboard or similar, that will help
the idea is to direct air over the front of the sheet instead of allowing it to pass under easily
I wasn't careful about this once and broke the first two feet of a sheet of paneling off when it folded back over the strap
>think of the hood popping up while driving...

>>1603849
That sounds wrong but even if it's not, I wouldn't use a big transformer made by harbor freight without a working ground. I also can't find an adapter that fits the outlet, here's a picture of the plug (can't even find a picture of the outlet).

>>1603722
If it's 220 you have either 2 hots and a ground(3 prong) or 2 hots, a ground and a neutral(4 prong). There are 2 ways to use it. The unsafe way would be using one hot with the ground as neutral. The inconvenient way would be to open the panel and disconnect one hot from the breaker and tie it to the neutral bus then wire an adapter accordingly. Neither are proper.

>>1603871
It has two hots with 120v on each. Anyway, this is only temporary; we'll be moving within a year or so. I need to fix some rust on my car before it gets worse. That second way sounds like it might be do-able though, thanks for the idea.

Tips for the Bennet mechanical test? I'm going to take one later today.

>>1603864

I'm not a big DIY person, but maybe someone can help me out. My window had a bug screen that didn't open or anything, so I ended up pulling it out last year to install my window AC unit. It has 4 little nail-like pins that need to be pulled back and sat into holes in order to secure it into the window frame.

I've tried over and over again to get the fucking thing back into the window, but kept dropping it outside by mistake because I could never get all 4 pins situated. (Would usually get one or maybe 2 in before the thing decided to tumble out of the window) I don't have anyone that can help me install it again. Is this supposed to be a one man job? Should I be using a ladder and trying from the outside instead? This is beyond frustrating. Can I just tape some fucking screen to the frame of my window instead? I honestly just want to use my box fan at this point and am sick of getting bugs in my room

>>1598487
Chinks to the rescue. Just use two..

How would I replace these small strips of wood around the window pane. I had to remove the old ones and they broke into a lot of pieces. Is it possible to cut something this thin, it's about a 1/4 inch on the thick side.

>>1604105
>these small strips of wood

it's window glazing, not wood. you put it on with a tool, putty knife, or your fingers, then let it dry for a few days, then prime and paint.

>>1604108
Thanks dude. My first time replacing a window pane so I had no idea. Thats super simple though.

>>1598031
How much heat can a 1 kwh battery generate, for example by running the current through cobalt wires? What would be the most efficient way to use a battery to generate heat and how much heat can I expect?

>>1604130
This might actually be a good question for /sci/ since this is basically a physics problem.

Either way you'll need to find out the resistance of the heating element, the voltage of the battery, and from there, you can use ohm's law to find the power draw of your heating element.

Actually if you think about it it's pretty much like like building a vape. Which is why I wouldn't recommend Cobalt at all? Nichrome is probably a safer choice.

https://en.m.wikipedia.org/wiki/Heating_element

>>1604130
Oh yeah I also wouldn't expect a very high efficiency for any heating element desu. But wtf are you even trying to do exactly?

>>1604134
>I also wouldn't expect a very high efficiency for any heating element

What are you saying here? A resistive heating element is 100% efficient.

>>1604136
Nothing irl is actually 100% efficient (although yeah it basically is here if you mean electricity to heat). But I suppose I should say that the heat might not 100% go where it's needed for whatever this guy is trying to do. So in that case there would definitely be a loss from heat just seeping into the surrounding environment and not into whatever he's trying to heat up...unless he's just trying to make a giant space heater....

>>1604133
Yeah I was thinking of nichrome not cobalt. I'm just playing around with the idea of living in a van, calculating heat loss in winter and how far batteries and solar can take me in the winter. I don't actually plan on living in a van I'm just bored. But anyway yeah apparently using electricity for heating is 100% efficient or near it, and even exceeds it using a heat exchanger.

>>1604151
If you do I'd just insulate the fuck out of the van. A battery powered heater could work but you'd need a fucking huge battery to run it for more than a tiny bit. Maradyne makes 12v heaters which use engine coolant like the heater core in your car already does. Ofc this won't work if the engine isn't hot/running but it will also save you from buying an overly huge battery. Just my 2¢.

>>1604158
Oh yeah a heated blanket would also be really effective at saving energy since you're directly heating your body and not the air. Same reason Tesla recommends using the heated seats over the heater.

>>1604158
Yeah, insulation is a given. Here are my rough calculations:

van wall surface area (excluding back and front): 2 meters tall 2.5 meters long = 5 sq meters * 4 (walls, floor and ceiling) = 20 sq m. 1 inch isoboard insulation = RSI-value of 1.2. for a 30 celsius temperature differential (from -10C to 20C), heat loss would be 30 / 1.2 = 25W/sq m. 25W/sq m * 20 sq m = 500W.

So a 1 kwh battery would be able to maintain a 30C temperature differential for approx 2 hours. I neglected heat loss from front and back but apparently the human body also emits 100W of heat constantly so that probably offsets some of it.

Batteries at their current energy density and price can't realistically get you through a Canadian winter. How solar would affect this is something I'll look into.

>>1604165
Yeah I was in Ottawa a few winters ago in Christmas when it was literally -30C over night. I doubt any battery would even hold it's charge at that temp considering how my phone acts just at 0C. And I'd be surprised if the solar panels would actually have enough power for heating. Probably could run some lights or charge a laptop but that's probably the extent of it. That being said, the heater blanket would probably be able to run at least twice as long and do a much better job at keeping you warm. Of course, besides that, or running the engine, layers help, but I assume you already are well familiar with that since you're Canadian.

That being said if you were in a van already I'd just drive somewhere warmer. At least that's what climbers like to do, chase the good weather.

>>1604171
Well, the battery would be inside the van so it would be heating itself by powering the heater, and the solar power would be charging the battery simultaneously. If a small battery (size of current 1kwh battery for example) could hold 2000+ kwh then getting through winter on battery power alone would be realistic. Of course it's easier to just travel south as you said, or live in a proper house/apartment. But it's interesting (for me at least) to toy around with the idea.

>>1604068
Looks like a homemade one

>>1604175
Believe me, when batteries reach that kind of density I'll be fucking exstatic and selling my car right away.

But for the time being if I need any huge batteries I'll probably just take them out of wrecked Tesla's. Funny part is that they're actually just 18650 cells (i.e. vape batteries) with a fancy load balancer and heating/cooling system.

Some time ago I was posting about my weed learning journey.

Big ones are developing pistils. They are getting only sun light.

I think that they will bloom too soon to deliver anything potent. Am I right? Or what should I expect?

>>1604208
Are they autoflowering seeds? Otherwise they won't flower until they have the right photoperiod (12 hours on/off) which outside would indicate wintertime. If they're getting 15+ hours of light a day then they shouldn't bloom at all.

>>1604208
And no, if they bloom early it will still be potent but your total yield will be far less than if they have more time to develop.

>>1600795
Derailleur cable and brake cable is different. The outer part and inner part is also different.

Some frames have multiple pieces of outer cable for the same brake/derailleur so I wouldn't know how many pieces.

Easiest thing to do is take all the old pieces to your local bike shop and they'll be able to cut a bunch of new parts to length for you. You'll also need an end cap wherever an outer cable is cut.

>>1600795
Also looks like your brakes are hydraulic so you'd want hose, brake fluid and a bleed kit if that were the case.

>>1604151
the efficiency of anything else is measured by how much energy is wasted... as heat
for example, a motor might be 80% efficient, the last 20% is wasted as heat
if heat is the goal, it's very easy to get basically 100% efficiency, the hardest part isn't turning electricity into heat, but rather directing that heat into the place you want it to go (minimizing atmospheric losses, unless you're making a space heater, in which case even that is easy)

>>1604151
>But anyway yeah apparently using electricity for heating is 100% efficient or near it, and even exceeds it using a heat exchanger.

Please go into detail about this "exceeding 100%" efficiency. Or patent your idea and put everyone else in the energy business out to pasture.

Thinking about using some kind of rope, string, or paracord to control/divert a small leak on a stationary hydraulic machine.

Anyone how any tips/into on what would be the best way to do this?

Alternatively, would anyone be interested in a 'rope and steel cable' thread?

>>1604322
Heat pump efficiencies are given as a multiple of a purely resistive heater’s efficiency (which is obviously 100% efficient at producing heat).
Would you agree that heat pumps heat a home with greater efficiency that resistive heaters? Or greater cost savings? That’s what people mean. You don’t have to like it but that’s how it is.

You guys know how to secure stuff in a patch panel with zap straps? I don't understand how to get the zap strap in through one hole and out another when the panel is already installed so there is no way to guide the zap strap from the back side. Right now some of my stuff is secured which the low voltage guy did, and other stuff that I got later on like the switch and new modem are kinda just hanging there. I have no idea how the guide the zap straps.

depends on what you're trying to do. Anyone can make you a drawing on some CAD program. You can prototype it with a 3D printer. The rest depends on the person/companies you're involving. Hell depending on how complicated it is I could probably draw it up for you in a couple of days in Solid Works.

I'm working on a small project. I have a hollow channel with a plastic insert which is the line inside the extrusion in pic attached. I need to be able to adjust the distance of the plastic by forcing it back in the direction of the arrow. The idea is that it would start close to the right and adjust it left as needed. I'm looking for some kind of plate with a spring or something like that, does anyone know what they're called or recommend something? When I google all I get are car parts.

>>1604649
>"it's acid in water"
Add the acid to water.
Other acids will work but you have to be careful of the strength and concentration.
Even vinegar will work but it takes longer and more of it.
Any strong toilet bowl cleaner should work on fresh rust stains.

I was wondering if someone can give me suggestion on piece of furnitures from ikea, I am wanting to buy a new hdtv off of amazon, probably 52 inch I am not sure yet.

I am looking for tv stand that can double as a dresser for clothes, too for my bedroom. I was thinking of this one
https://www.ikea.com/us/en/catalog/products/30311307/

I am wanting to keep it under 200 dollars USD, and make it light so I can carry it when I need to move, not full wood heavy as fuck.

I'll take suggestions too.

>>1605027
You’re not looking for a TV stand, you’re looking for a dresser.

It’s all the same flat pack bullshit. For under $200, buy whatever laminated particle board fits your room best. Ikea and Walmart and the other big box stores will sell you the same crap.

>>1605031
Essentially yes a dresser, where I can put a tv on top, which the one I linked seems to be just fine.

what is this and do I have it on upside down.

>>1605031
>Ikea and Walmart and the other big box stores will sell you the same crap.

Ikea instruction are clear and easy to understand, I've never had a missing screw or missing pre-drilled hole or something like that. I've had minor problems with most other brands, the kind talked about in "Ikea joke".

As strange as it sound, Ikea is high quality among particulate board furniture stores.

Idk about walmart in particular.

>>1605027
If the TV is heavy and you intend on keeping the dresser for years, make sure there is a vertical board in the middle (so a 2 or 4 drawers wide dresser, not a 3 drawers wide one) and maybe add a feet in the centre (like some TV stands have)

>>1605108

I use dead trees for filling garden beds. Dead trees are really good at absorbing moisture and it will be a fertile place to garden if you do so. (this practice is called hugelkulre). Eventually the trees will rot and turn into soil so I think you're all good.

I bought some cheap LEDs off the Chinese, I was going to wire them up and stick them on the back of my monitor for backlight, but it turns out they give off more heat than I'd anticipated.

Now, would it be a stupid idea to stick them onto some copper tape to serve as a heatsink? They're not too strong, so I feel like it could work.

Friends, could one of you help me out, what kind of (interior) door is pic related? I thought it was four panel, but that doesn't seem to be the case.
I ask because the top square panel has been smashed. Is it at all feasible to replace this panel, or am I just best off buying a new door? It's all wood, no glass or nothing. I'm not even sure of the type of wood. The doors aren't hollow, they're solid, but the wood almost feels soft enough to have a bit of give when you push on it.
Sorry I don't have a pic, just my artist's rendition. Any help would be appreciated.

>>1605954

French doors. Your's is a bit odd, though. They usually come in pairs, with about 3x6 sections, and have glass inserts instead of wood. I'd say someone who wasn't too good at making doors was involved.

>>1605962
Thanks for the help friend. I did find them once before (individually), but I just haven't been able to find them since. They're very odd, very tall and very narrow, but I suppose that's more owing to the size of the door frames.

want to make a room within a room. dimensions will be 8.5 feet long, 6.3 feet wide and 6.5 feet tall. if I make this thing out of 2x4s nailed together will it be relatively solid just on the wooden floor in my room?

>>1605971
>if I make this thing out of 2x4s nailed together will it be relatively solid just on the wooden floor in my room?
That should be pretty solid.
Yes. Are you making a soundproof masturbation enclosure? If you are, you should float the floor too.

>>1605973
>Are you making a soundproof masturbation enclosure?
Basically yes. Also the insulation in my apartment is piss poor so it's cold as fuck here in winter. And I can't sleep with the AC because it's too loud, so this room should isolate me from that noise while venting the cold air into the little enclosure. Might even make a peltier AC for the small room.

>>1605974
Be aware that if your air conditioner has a deep, low frequency hum, it may be near impossible (or too expensive) to attenuate that low frequency component - and that may be the noise that annoys you the most.
t. built a soundproof room-within-a-room cuckshed in the back yard of my property ~100ft from a busy road
The white noise rush of traffic is now inaudible, but the low frequency thump of motorcycle engines, trucks, and occasionally car music is still faintly audible.

>>1605981
Any tips for soundproofing?

>>1605984
The 4 magic words with soundproofing are decoupling, damping, airtightness, and mass. Jewgle "room within a room soundproofing" and "sound transmission mass law" to get started.

The closer to 100% airtight your room is, the better. If the door has open air gaps, there is quite a noticeable, measurable difference in sound transmission compared to sealed gaps.
More mass is better, so use use 5/8 drywall instead of 1/2, and try to avoid any drywall which is low density "ultra light" stuff. Two layers of 5/8 drywall, with Green Glue sandwiched between, is even better.
I used safe'n'sound roxul rockwool for my build, which is excellent for attenuating the high frequencies, but doesn't help for low freqs.

You may also need to float your room on rubber U's or rubber pucks. I didn't float my room because it was on a concrete pad.

My buddy has a bunch of crosscut saws that are all dull as fuck. Is it worth sharpening them in the modern day?

>>1605954
'mission' style has similar panels (in some cases)
finding the style of door won't help with the broken panel
panels aren't sold individually
you'll have to make or have made a custom replacement panel
breaking the door down to replace the panel is probably not worth it unless it's a special case
(history, heritage, etc.)
if the door originally had glass in the top panel, there may be removable glazing trim which can be taken off to replace the panel

Ill probably ask again next thread, but I have a need for some material that isn't complete garbage to be 3mm thick. my keyboard tray is a bit iffy, and if I get a 3mm piece of wood or something to put on the thing, I would be able to get any mouse pad I want as a replacement rather then just looking for 3+mm thick once.

How much weight does the 3mm plate need to support - all of it? or is the 3mm being added to something else? plexiglass or aluminum might work...

I use a hydraulic ram at work, basically 2 inch wide steel tube. I want to put a bunch of stupid stickers on it but they'll peel instantly. This ram on any given day can be blasted by naptha, acids, crude oil, asphalt, gas oils and a ton of other caustics or solvent. I was thinking some epoxy resin to coat it.

Could be the washing's machine discharge too (it's right next to the boiler) so I want to check whether there's a real leak or not, because calling the expert at this time of the year is kinda costly, usually the free check from the boiler's brand company comes once a year in october but I was absent last time.

They instruct to apply tin to the iron tip, and seem to do that by just touching the hot tip with the tin.
However, when I do that, the tin forms a bead which stick to itself instead of the iron tip.

Am I doing something wrong ? Do I have the wrong kind of solder tin ?
It seems to be made of 97% tin, 2% rosin, 1% copper.

>>1606928
I'll try that even though the pipes look fine, I think if there's something it must be inside the boiler itself. The odor isn't strong and it happens only sometimes, that's why I'd exclude the pipes, if there was a hole or a loose connection I bet the odor would be getting stronger.

>>1606930
How oxidized is the tip? I made that mistake when I first started, solder won’t coat the tip properly once you let it get fucked.

Also everybody here hates unleaded solder. I don’t have enough experience but the real leaded stuff seems to flow better.

>- why does the thickness of your desk impact the thickness of your mousepad?

cant give photo, no working camera due to sd card fucking itself.

the desk has a bout 70x36cm of wood, with some sides that are made of metal for rolling in and out.
the sides however stick up just shy of 8mm and as its where my mouse is, my wrist regularly sits on it
I put a bit of the mouse pad over it, and while it does help, there is still a spot that is bumped up over the side that my hand rests on. and its not comfortable.


looking at its construction, i could get some wood that is 3/4ths thick... did not consider that as an option at first as I didn't notice the screws, hell I could even make it deeper than that too as I regularly need to move my keyboard off the tray when I bring up my drawing monitor. well... got some shit to consider now. I could go 3/4 thick and get to where I wanted it to be, or I could just say fuck it and glue some 1 by 4 or some 1 by 6 together... only real problem is I have shit tools to work with so glueing will be a motherfucker for me along with not fully trusting glue to hold... but it would only be holding a 3lbs keyboard and sub 3 ounce mouse so I think even fucking elmers would work.

>>1607166
interesting. our shop carries the red ones in bulk so that's what I primarily use. If your hole is just the right size, the only way to get em out is by having a screw halfway in and yanking mega hard with linesmens. Some camera's that I mount come with one of those spiral ones, and twice I've tried to use one but it ends up falling apart if I have to loosen the screw a bit. Maybe they're just shipping with shit ones, I'll have to try em again sometime

>>1607206
>the only way to get em out is by having a screw halfway in and yanking mega hard with linesmens
Use an oversize screw so it grips at the opening without having to go in far enough to spread the 'fingers'.
Pull it out with your bare fingers.

>The odor isn't strong and it happens only sometimes,

Could be a burner problem. Or the igniter (pilot light) isn't starting the main flame properly. You get a puff of raw gas until it gets going.

>>1607139
could be one cylinder running lean (not enough fuel), could be one cylinder not burning the fuel completely (wrong plugs). check the plugs, see if one is blacker than the other. could even just be old plugs, desu. if it is, take it to the parts store and ask for a plug that is one step hotter

So dumb question
I have an air pipe .307ish OD and i need a compression fitting (its an air compressor) to seal the outlet tube. i find 5/16 fittings (.3125) as the closest size. Is this too much of a size difference for it to compress down to?

>Ride on mower drains batteries

Would a ride on mower draw more than 100A on startup?
Should I put it on the + on - side of the battery?
I don't want it to trip, I just want to press the button to manually trip it when I'm done with the mower.

>>1607332
>Should I put it on the + on - side of the battery?
+ side

so in trouble shooting my ceiling fan problems I figured out the screws holding the entire assembly to the ceiling were wobbling, well it turns out the holes themselves are stripped borderline bare.


Is there anything I can do to "fix" it so I can secure the assembly to the ceiling?

I was thinking of getting two new screws 1 size bigger and just forcing them through to "rethread" it, is that a stupid idea?

Yeah, the tip was almost black, I realised it wasn't normal after watching more videos.
I replaced it with a new one and it worked perfectly.
I will be careful to properly tin the tip before storage in the future.

Heyyo /diy/nos. I'm peeling off my metal roofing because whoever installed it before I got the house did a shit job and left orientated strand board (osb, the shitty pulp plywood stuff) exposed to moisture so it started to rot ofc. This portion of the roof was built with osb over tongue and groove boards. My problem is as follows:

In an area facing direct sun, the osb looked fine, but I noticed the tongue and groove boards underneath were black between the gaps, so I pulled the osb off to find that the tongue and groove boards were charred. Not rotted, but charred. Only on the upaward facing side nearest the perimeter of the roof, too. Below this section of roof, there is a big hot window next to a glass door that absolutely bakes the hallway in the summer, so I'm thinking maybe that was the cause? I am absolutely baffled by it and not sure how to proceed (yes, I have the same tongue and groove boards handy - just not sure if I should toss them in there without figuring this out).

Thanks!

hit enter too soon. It is probably one of these screwed into a stud. can get them for a few bucks at HD. Unscrew old one, screw in new one. Now it MIGHT be one of these weird ones that lets you position it between studs. not a big deal, just a bit more work.

I have a bundle of 5 cat 5e cables running from where my TV is mounted and in the wall to a cabinet. Neither end of any of the cables have keystones because, I assume, the low voltage guy is a lazy shit. What I'm wondering is why anyone would need that many cat cables running to their TV. One can be used for a wired Ethernet connection for a smart TV, but that leaves 4 cables that are just there.

so when you put anchors in, you drill the hole big enough to be able to slide the anchors right in?

i've always made them slightly smaller, so you have to bang the last 1/4" or so in w/ a blunt object. not possible to pull that out with bare fingers

>>1607737
>so when you put anchors in, you drill the hole big enough to be able to slide the anchors right in?
No. I make the hole undersize and force the anchor in.
>>1607737
>not possible to pull that out with bare fingers
Don't pull on the anchor. Pull on the oversize screw that you used to catch on just the opening of the anchor.
If you can't get the hang of it, ask your girlfriend to do it for you.

>>1607743
yeah I literally described that pulling on the screw method in my second post, but sounds to me like ur drilling them holes a lil too big

Eurofag here. What is the usual power system for industrial/workshops/machinery in the US? Is it the same as here (three 120 degree phases, 400V between them)?

>>1606864
>gas odor
Where I live (Illinois) the gas company will come and investigate gas leaks 24/7 for free and they'll be there within an hour. Gas is pretty distinctive so if you catch a whiff there's probably a leak.

Idk if this is the case everywhere, but when they come they sweep the place and if the leak is above a certain level they'll turn off AND LOCK OUT the gas until you can get it fixed. Generally if you can smell it at all the leak is big enough that they're gonna shut it off. If it's genuinely a small leak I'd line up a repairman to come out before you call the gas company because 1) they lock it out and 2) once the job is done they take their sweet time coming back. They lit the pilot lights for me too.

Home workshops are typically single-phase 120V, with single-phase 240V used for larger machines in better-equipped home workshops. Standard residential supply is single phase 240V, so that's usually fairly easy to set up. Three phase is very rare in a home shop. Industrial machines are usually three-phase, but voltage standards vary. 200-480 volts is fairly common, but it can go higher. Industrial facilities also have single-phase 120V power to run small tools and miscellaneous items.

I am going back to school and I am not sure what to do.

Its between an advanced welding certification and an associates in construction management.

Both take about the same amount of time but I am unsure about the payoff and need to find an actual profession quick.

Would an associates in construction management even mean anything to most employers?

Thanks.

>>1609244
check and see which field has the most openings
lean toward one you WANT to do

>>1609286
I appreciate the response.

I live in Houston- welding/manufacturing is up ~10%.

I am thinking welding for real skills that transfer to a real job.

Mom wants college degree- says friend can get me a job no matter what degree with Dow but this is third hand. I figure construction mgmnt. so that whatever I get is real world applicable- but is that even true?

I am not sure that someone looking for skills or even management in this field would care unless I knew someone.

I am paying for it all and its my future but just not sure...

So my real ques

Also when I look into welding the pay isn't great.'

Is there a field I am forgetting?

I am not sure. I was taught to know a little about a lot of things- now that I am older I found I am sort of a jack of all trades but a master of none- I am mediocre. No real passion. I know I could devote to something but kind of ambivalent towards it all.

I still have to decide though.

are smiths of ye old dead? everything related to metallurgy seems to be made through machinery nowadays
I'm not really that interested in becoming a machinist. the most similar trade seems welding, but smiths do more things besides welding, don't they?

Hello. My dishwasher is giving me an error signal but the vendor just wants to send me to some bullshit repair shills instead of troubleshooting my problem. I think I might need to replace the control board, but am hesitant to engage the parts cannon before I've tried finding all the different options for resetting or tricking the unit into working again. The manual doesn't list this specific error code.

I need to kill some English ivy. It's growing in the neighbor's yard though. It's very well established and covers their whole wooded area and is covering most of their trees. Thinking about grabbing the vines that crawl under my fence into my yard, cutting the tips, abrading the leaves, wrapping them in gauze bandage, then soaking the gauze in roundup. Maybe I'll make a whole line of solo cups full of roundup for the vines to soak in. I know that this ivy came from a single planting, so I'm hoping all of it is one big plant. What do you think? Would this work?

Let it dry out with the door open, shut off the breaker for ten minutes. If that doesn't work, open it up and see if there are corroded connections. Make sure all the seals and gaskets are installed properly to keep steam out of the electronics.

This window won't close, this thing is supposed to be attached to the window and slide with it, but its wedged or something. I think the metal u thing rotates to lock it to the window.
